Although increasingly recommended, compliance with low Vt ventilation remains suboptimal. Dyssynchrony induced by low Vts may be a reason for it. ⋯ Lower Vts during VC ventilation result in higher patient-ventilator dyssynchrony in most patients with or at risk for acute respiratory distress syndrome. The use of APC mode is an option to reduce dyssynchrony, but it requires careful monitoring to avoid larger-than-target delivered volumes.

Communication in the intensive care unit (ICU) often falls short of patient and family needs, putting them at risk for significant physical and emotional harm. As electronic patient portals rapidly evolve, one designed specifically for the ICU might potentially enhance communication among patients, family members, and clinicians; however, the views of frontline ICU staff on such technology are unknown. ⋯ Overall, clinicians were cautiously supportive of an electronic portal to enhance communication in the ICU and made several specific recommendations for design and implementation. As new technologies expand opportunities for greater transparency and participation in care, clinician buy-in and positive impact will depend, in large part, on the extent to which the concerns of stakeholders are addressed. At the same time, clinicians anticipate several potential benefits that could help support provider workflow and engage patients and families through enhanced communication and humanism.

Many nontuberculous mycobacteria (NTM) are clinically significant pathogens that cause disease in a variety of different human organs and tissues. ⋯ From 2008 to 2013, the number of patients with positive specimens for NTM rose. This trend is likely to continue in the coming decade as the U.S. population ages. To reduce the prevalence of NTM infections, medical guidance for susceptible populations is needed regarding actions that can be taken to avoid sources and routes of exposure to NTMs if the disease burden is to be reduced.

Multicenter Study
Lung Function Trajectory in Bronchiolitis Obliterans Syndrome after Allogeneic Hematopoietic Cell Transplant.
The natural history of lung function in patients with bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic cell transplant is poorly characterized. Understanding the trajectory of lung function is necessary for prompt clinical recognition and treatment and also for the rational design of prospective studies. ⋯ The FEV1 trajectory in patients with BOS after hematopoietic cell transplant in a contemporary era of management follows a predominant pattern of rapid FEV1 decline in the 6 months prior to diagnosis, followed by FEV1 stabilization after diagnosis.
